how to know if implementation with a filter value exist for a BAdI in code?

Hi all,

Scenario:

I created a BAdI. There will be a button on the UI to call its implementation(s); while if there is no implementation with specified filter value, this button needs to be hidden. Thus I need to know if the implementation exist before calling it.

Question:

In the ABAP code, how to get whether implementation with specified filter value exists for a BAdI?

If it's possible, please help provide code.

Thanks and regards,

Said
